DISCUSSION
TODAY THROUGH THURSDAY...
ENERGY UNDER SOUTHWEST FLOW PROVIDED SHOWERS AND THUNDERSTORMS
THIS EVENING AND WILL BRING ANOTHER ROUND EARLY THIS MORNING. WITH
LOW INSTABILITY FORECASTED, WEAK ISOLATED THUNDERSTORMS ARE
EXPECTED. THE MAIN THREAT WITH THESE STORMS WILL BE WIND GUSTS
30-40 MPH AND HEAVY RAIN. CONDITIONS WILL COOL FOLLOWING THE WEAK
FRONT, KEEPING HIGH TEMPERATURES IN THE 70S TO LOW 80S FOR SOUTH
CENTRAL MT WITH HIGHS IN THE 80S TO LOW 90S FOR THE REMAINDER OF
THE AREA. A SIMILAR SETUP IS EXPECTED FOR SATURDAY, HOWEVER THERE
IS STILL SOME UNCERTAINTY ON HOW WIDESPREAD THE SHOWERS WILL BE. A
FEW STRONGER STORMS ARE POSSIBLE ACROSS SOUTHEAST MT AS DAYTIME
HEATING WILL ALLOW FOR BETTER INSTABILITY. AS UPPER LEVEL
TROUGHING APPROACHES FROM THE PACIFIC NORTHWEST SUNDAY, STRONGER
FORCING WILL YIELD A 40-70% CHANCE OF PRECIPITATION ACROSS THE
REGION ALONG WITH A FEW STRONG THUNDERSTORMS. WITH ELEVATED
PRECIPITABLE WATER VALUES OF 0.9-1.3", THERE IS A RISK FOR HEAVY
RAIN WITH ANY THUNDERSTORM. STRONG SUBSIDENCE WILL YIELD DRY AND
BREEZY CONDITIONS BEHIND THE FRONT SUNDAY EVENING, BUT THIS WILL
BE DEPENDENT ON THE TIMING AND LOCATION OF THE FRONT. ENSEMBLES
BRING RIDGING BACK FOR MONDAY BEFORE TRANSITIONING BACK TO AN
SOUTHWEST FLOW BY MIDWEEK, INCREASING CHANCES FOR AFTERNOON
SHOWERS AND THUNDERSTORMS. BY THURSDAY, ENSEMBLES ARE HINTING AT
MORE PRONOUNCED TROUGHING APPROACHING FROM THE PACIFIC NORTHWEST.
HIGH TEMPERATURES ARE EXPECTED TO SLIGHTLY COOL OVER THE WEEKEND
INTO THE 70S AND 80S, WARMING BACK INTO THE 80S AND LOW 90S BY MID
WEEK. TS
AVIATION
SCATTERED TO WIDESPREAD SHOWERS AND WEAK ISOLATED THUNDERSTORMS
ARE AGAIN EXPECTED THIS MORNING THROUGH THE AFTERNOON. GUSTY
WINDS 30-40 KTS WILL BE THE MAIN CONCERN. WILDFIRE SMOKE WILL
AFFECT SLANT RANGE VISIBILITY THROUGH THE DAY. ADDITIONAL
SCATTERED SHOWERS ARE EXPECTED TONIGHT INTO SATURDAY. TS
